Photorec creating custom file signature for identification

#1 Post by spano »


I have been trying to create my own signature to identify files that i am looking for on my damaged SD card using the instructions found here: ... o_PhotoRec

I have a bit of a problem though. The files I am looking for are JPG images that are encrypted. As a result, the common header on the file that indicates that it is a JPG file is not "readable". Also the encrypted JPGs do not seem to have any particular signature that I can use to identify them.

What I do notice is that the file names are available. Am I able to create a signature that just uses photorec to extract all *.jpg files?

I tried creating a signature with just jpg in it but fidentify is unable to identify it. If i create something like this I am able to identify the file (but it is too specific)
